How to Install macOS on ASUS ROG G15 Ryzen 6800H: Integrated GPU Limitations and Workarounds

Attempting to Hackintosh a modern AMD Ryzen-based gaming laptop like the ASUS ROG G15 (featuring the Ryzen 7 6800H CPU and an NVIDIA dGPU) introduces severe hardware restrictions. While macOS can run on AMD CPUs with kernel patches, the integrated Radeon 680M graphics (RDNA2) and the dedicated NVIDIA card have zero driver support under macOS. This guide outlines these limitations, BIOS configurations, and realistic alternatives.

1. Prerequisites

• Hardware configuration: ASUS ROG G15 laptop, AMD Ryzen 7 6800H CPU, AMD Radeon 680M iGPU, NVIDIA RTX 30-series/40-series dGPU.
• Required tools: OpenCorePkg, ProperTree, GenSMBIOS, NootED.kext (experimental).
• Warning: Because RDNA2 graphics are not supported, you will have no GPU acceleration in macOS, resulting in sluggish UI performance and broken sleep/wake functions.

2. Compatibility Snapshot

• NVIDIA dGPU: Completely unsupported. Must be disabled using boot arguments like -wegnoegpu.
• AMD Radeon 680M iGPU: No support in current macOS graphics drivers. NootED only supports Vega/RDNA1 architectures.
• Ryzen CPU support: Fully functional for basic CPU calculations using custom kernel patches.

3. Installation Preparation

1. BIOS Settings: Disable Secure Boot, Fast Boot, and AMD SVM (virtualisation, unless required, in which case configure virtualization kexts). Set graphics mode to Eco or iGPU-only in ASUS Armoury Crate (under Windows) before booting OpenCore.
2. Partition Storage: Shrink your Windows partition to make space for macOS APFS formatting.

4. EFI and config.plist Review

1. Kernel Patches: Add the official AMD OS X CPU patches to your config.plist.
2. Essential Kexts: Add Lilu, VirtualSMC, NootED (keep disabled if it loops, or run VESA mode), and ethernet drivers.
3. Boot Arguments: Use -v keepsyms=1 debug=0x100 -wegnoegpu to disable the NVIDIA graphics completely.

5. Post-Installation

1. VESA Mode Usage: Understand that the system will run in VESA mode (unaccelerated framebuffer). Display rendering is done entirely by the CPU.
2. Audio Config: Identify the Realtek audio codec and inject the layout ID via alcid= boot arg.

6. Troubleshooting

Reported Issue: Stuttering UI and Graphics Lag

1. Unaccelerated Graphics: Without a supported GPU, window dragging and browser scrolling will feel choppy. This is normal behaviour for unaccelerated framebuffers.
2. Kernel Panic on Boot: If the installer panic loops at AMD CPU checks, double-check your kernel patch values in ProperTree.

Common Hackintosh Checks

• Ensure XhciPortLimit is set to false to prevent USB initialization stalls during installer boot.

7. Dual Boot and Advanced Configuration

• Windows Priority: Keep Windows as your main OS for gaming and productive work where dGPU acceleration is required. Use macOS purely for software development testing.

8. Verification, Maintenance and Rollback

• Verify: Open System Settings -> About This Mac. The graphics driver should read "Display 7 MB" or similar unaccelerated designation.
• Rollback: Delete the macOS EFI folder partition if you decide to revert to a Windows-only configuration.
